Research indicates that matcha, once considered a ceremonial drink limited to Japan, has now become an integral part of beverage menus in cafes worldwide. According to market research firm NIQ, matcha sales in the United States have seen a remarkable increase of 77% over the past three years, reflecting a growing interest among consumers.
Many believe that the caffeine in matcha is absorbed more slowly compared to caffeine in coffee, resulting in a feeling of "calm alertness" without anxiety or sudden energy crashes. But does research support these benefits?
Details of the Drink
Matcha is a type of green tea that is dried and ground into a fine powder. Unlike other green teas that are grown in full sunlight, matcha plants are typically shaded using straw, cloth, or plastic nets for several weeks before harvest. This process increases the concentration of certain compounds, including chlorophyll, which gives the tea its vibrant green color.
Matcha is prepared by whisking the powder into hot water rather than steeping it, resulting in a drink that contains higher concentrations of caffeine, amino acids, and antioxidants. According to Dr. Marlene Cornelis, a nutrition professor at Northwestern University, matcha can be considered an "enhanced" green tea.
Background & Context
Caffeine levels in coffee and tea vary significantly, but matcha typically contains more caffeine than regular green tea and less than coffee. According to the U.S. Department of Agriculture, eight ounces of green tea contains about 30 mg of caffeine, while the same amount of brewed coffee contains about 100 mg, with stronger cups potentially containing more. Although standard nutritional values for matcha are not available, a scientific review from 2020 suggests that matcha powder can contain between 19 mg and 44 mg of caffeine per gram of powder.
If a matcha drink is prepared using a teaspoon of powder, this translates to between 38 mg and 88 mg of caffeine per serving. Dr. Cornelis noted that matcha may provide an "ideal" dose of caffeine for some individuals, sufficient to boost energy without causing anxiety or insomnia.
Impact & Consequences
Despite the potential benefits, there is no conclusive evidence supporting the idea that caffeine in matcha is absorbed more slowly. Some marketing for matcha drinks suggests that certain compounds in the tea can reduce stress and enhance focus. For instance, L-theanine, an amino acid found in matcha, is believed to help reduce stress, and when combined with caffeine, is associated with improved focus.
However, the studies conducted have been small and limited, often examining the same compounds in supplements or other drinks rather than in matcha itself. Studies examining the health effects of matcha have shown mixed results.
Regional Significance
As the popularity of matcha grows worldwide, it may impact dietary habits in Arab countries. Arab consumers may find matcha a healthy alternative to traditional coffee, especially if prepared healthily without adding excessive sugar. It is important for consumers to be aware that many popular matcha drinks, such as lattes or bubble tea, may contain high amounts of sugar.
In conclusion, matcha presents an interesting option for those seeking healthy alternatives, but it is essential to ensure the preparation methods and ingredients used to maximize the benefits of this drink.
